  Synthesis of 2,6,7-Trichloro-1-(β-d-ribofuranosyl)naphtho[2,3-d]imidazole:  A Linear Dimensional Analogue of the Antiviral Agent TCRB

  摘要：

  Human cytomegalovirus (HCMV) remains a significant clinical problem in neonates and immunocompromised individuals such as those undergoing transplantation as well as individuals with acquired immune deficiency syndrome (AIDS). Recently in our laboratory, 2,5,6-trichloro-1-(beta-D-ribofuranosyl)benzimidazole (TCRB, 1a) and 2-bromo-5,6-dichloro-1-(beta-D-ribofuranosyl)benzimidazole (BDCRB, 1b) were found to have better activities in cell culture studies against HCMV than the clinically used agents ganciclovir and foscarnet. These benzimidazole compounds appear to act by a unique mechanism. However, as the biological target of TCRB and BDCRB has not been completely identified, 2,6,7-trichloro-1-(beta-D-ribofuranosyl)naphthol[2,3-d]imidazole (2) was designed as a linear dimensional analogue of TCRB for a study on the spatial limitation of the binding site in the target enzyme. In the synthesis, a convenient route was developed for the synthesis of 2-substituted 6,7-dichloronaphtho[2,3-d]imidazoles involving a Diels-Alder reaction of 4,5-dichloro-o-quinodimethane (8) as the key step. 6,7-Dichloro-1,4-dihydro-2,3-benzoxathiin 3-oxide (15) was found to be an ideal precursor for the generation of the elusive intermediate 8. The ribosylation of 6,7-dichloronaphtho[2,3-d]imidazoles was influenced by the functional group at the 2-position and 6,7-dichloro-2-methylthionaphtho[2,3-d]imidazole (3c) was found to smoothly undergo ribosylation. The 2-methylthio group of the unprotected nucleoside 25 was converted into a chloro group under mild conditions to give nucleoside 2 in high yield.

  The polyhalogenated benzimidazole nucleosides 2,5, 6-trichloro-1-(beta-D-ribofuranosyl)benzimidazole (TCRB) and the 2-bromo analogue (BDCRB) were synthesized in our laboratory and established as potent and selective inhibitors of human cytomegalovirus (HCMV) with a novel mode of action. In an effort to study the behavior of the key substructure in a dimensionally extended manner and probe the spatial

  在我们的实验室中合成了多卤代苯并咪唑核苷2,5、6-三氯-1-（β-D-呋喃呋喃糖基）苯并咪唑（TCRB）和2-溴类似物（BDCRB），并将其作为人巨细胞病毒的有效和选择性抑制剂（ HCMV）具有新颖的作用方式。为了研究关键亚结构的行为，在尺寸上扩展并探究目标酶的空间限制，一系列了2-取代的6、7-二氯-1-（β-D-呋喃呋喃糖基）制备了萘酚，2,3-二咪唑和2-取代的6,7-二氯咪唑-4、5-喹啉的N1-和N3-核糖核苷。核苷6、7-二氯-1-（β-D-呋喃呋喃糖基）咪唑4,5-bquinolin-2-one和6,7-二氯-3-（β-D-核呋喃糖基）咪唑-4,5-选择了bquinolin-2-one，并将其用作咪唑4的关键合成中间体，5-喹啉系列。对化合物针对HCMV和1型单纯疱疹病毒的活性进行评估后发现，TCRB的三氯类似物（2a，3a）对HCMV的活性与TCRB几乎相同，但具有更高的
